Profile: Jacob Turner had a good season in the minors in 2011 and is considered a top pitching prospect by many. His throws a low-to-mid nineties fastball, a high 70’s curve that he has tightened up a lot, and a mid-eighties changeup. In limited action in the majors both his changeup and curveball generated a lot of swings-and-misses, but we must be wary of the sample size. His fastball is purported to have great downward movement, but based on his groundball rates in the minors it’s unlikely that he will generate a lot of grounders in the majors. A concern about his numbers in the minors is that at Double-A this year he struck out 7.13 per nine -- not what we would expect given the glowing scouting reports and hype. While Turner could use more seasoning, the Tigers are known to be aggressive with their prospects, so it’s possible that he could start next season as the fifth starter. Given the playing time and performance concerns, it’s best to be cautious about Turner. (Josh Weinstock)

The Quick Opinion: Despite glowing scouting reports, Turner needs more seasoning in the minors. While he provides a good deal of upside, don’t expect him to provide much value in 2012.

Profile: Acquired by the Marlins in July, the top pitching prospect had a mediocre debut in his second taste of the Majors. While he has shown a slight ground-ball tilt and good control, his strikeout ability was underwhelming. His minor league strikeout rates were also unimpressive; however, he did manage to induce an above league average swinging strike rate, suggesting that maybe his strikeout rate could approach the high-six range. The move to the National League and a pitcher's park is definitely a positive for his long-term fantasy outlook, but at the moment, he appears to have limited upside. (Mike Podhorzer)

The Quick Opinion: Turner is expected to open the season as a member of the Marlins rotation after a trade from Detroit brought him to Miami. However, with weak offensive support likely curtailing his win potential and uninspiring strikeout rates dampening his fantasy value, his appeal is limited to NL-Only or deep mixed leagues.

Profile: Jacob Turner got the call to the Marlins late in May and didn’t look back, starting 20 games with a 3.74 ERA. Despite the impressive sophomore campaign, there are troubling signs beneath the surface, ones that the 23-year-old has plenty of time to figure out. Most pressing is his inability to strike batters out – he has just a 15% strikeout rate in 185.2 major league innings, hardly surprising given his minor league track record. What’s curious is that despite showing strong control in the minors, Turner struggled with walks (4.12 per nine innings) in 2013. In any case, Turner has looked largely the same whenever he’s been called up, with only strand rate, batting average on balls in play and home run per fly ball variations swinging his stat line. You could say split the difference between the years (maybe a 4.50 ERA), but experience, a decent slider, and an improving curveball that can draw whiffs and ground balls leave room for optimism.

The Quick Opinion: Jacob Turner still has time to deliver on his promise, but his 3.74 ERA in 2013 masks the fact that he still has trouble missing bats. His curveball, a pitch he doesn't use a ton but that performs well for whiffs and ground balls, may hold the answer.

Profile: The Angels once had a highly thought of right-handed pitcher with gas, good breakers, and a bad changeup. It took him a while to become the Garret Richards we know now, but it happened when he decided to turf the bad change and go fastball/slider/curve. Now the Cubs have former top prospect Jacob Turner, and he's still averaging 92+ with the fastballs, still showing good whiff rates on the curve (13%, 11% is average) and slider (15%, 13% is average), and still has one last chance to make it. He's behind a lot of people if he wants to get into the rotation -- Tsuyoshi Wada, Edwin Jackson, and Travis Wood at least -- but at least none of those names represents an insurmountable obstacle. Even if he ends up in the pen, Hector Rondon, Pedro Strop, and Neil Ramirez also don't scare the fantasy upside out of him. Especially if he's more 94 than 92 in the pen. There's some talent in this arm. Wait for the dust to settle on roles, and consider making a deep league bet commensurate with his upside -- decent closer, mid-rotation starter -- late in your late-spring deep-league draft.

The Quick Opinion: Jacob Turner has decent control, two breaking balls that are above-average by whiffs, and above-average velocity as a starter. That's enough to keep an eye on his role, and enough to remember that he was once a top prospect. You might see this name again in 2015.

Profile: Once a former top prospect, the last time Turner pitched well for an extended period of time was in Detroit's minor league system in 2011. Since then he's been with the Marlins and Cubs and was claimed off waivers by the White Sox late last year. But with the White Sox he finds himself in a spot where he could potentially be needed in the rotation. There are definitely five guys ahead of Turner for rotation spots, but were the Sox to need another starter, Turner may well be the next guy up. With a couple of decent breaking balls and some decent velocity the last time he pitched in the majors (2014), he's a name for those in the deepest of leagues to keep in the back of their mind. (Brett Talley)

The Quick Opinion: Turner threw just nine Double-A innings in 2015 due to injuries, and he now finds himself with the White Sox, his fourth team in his young career. With the White Sox he could be the next man up if any of their five planned starters need replacing. When Turner last pitched in the majors he showed decent velocity and two decent breaking pitches, so deep leaguers could give him a look if he ends up in the rotation.
